PROBLEM TO BE SOLVED: To form a clock multiplex signal transmitted from a transmission device to a reception device in a simple clock circuit and to directly reproduce a clock signal from the received clock multiplex signal without using an expensive and complicated circuit such as a PLL circuit in the reception device. SOLUTION: The transmission device TQ1 provided with a parallel/serial conversion circuit 1 which converts parallel signals S1 -S8 inputted by a transmission-side clock signal ϕ1 into serial data transmission signals f1 , and with an encoding circuit 2 encoding the serial data transmission signals and outputting the clock multiplex signal f2 is provided. The reception device RQ1 provided with a decoding circuit 12 decoding the clock multiplex signal and outputting a serial data reception signal f4 and a reception-side clock signal ϕ2 and a serial/parallel conversion circuit 13 converting the serial data reception signal inputted by the reception-side clock signal into parallel signals O1 -O8 is provided. |
